Key result
Zone 2 Frozen Elephant Trunk (FET) is increasingly preferred over Zone 3 FET due to technical simplicity and reduced risks of spinal cord injury, visceral ischemia, and cardiovascular sequelae.
Why the study?
Surgical preference has shifted from Zone 3 to Zone 2 FET, but comparative literature remains scarce, observational, and anecdotal.
Does Zone 2 Frozen Elephant Trunk (FET) improve outcomes and reduce complications compared to Zone 3 FET in patients with complex aortic pathologies?
Population
Patients with complex aortic pathologies involving the distal aortic arch and proximal descending aorta

May favor Zone 2 over Zone 3 FET; leaves open need for randomized confirmation in aortic arch repair.
Does Zone 2 Frozen Elephant Trunk (FET) improve outcomes and reduce complications compared to Zone 3 FET in patients with complex aortic pathologies?
This review highlights the shift in surgical preference toward Zone 2 FET over Zone 3 FET due to its technical simplicity and reduced risk of ischemic and neurological complications.
Choudhury et al. (2021) conducted a review in complex aortic pathologies. Zone 2 Frozen Elephant Trunk vs. Zone 3 Frozen Elephant Trunk was evaluated. Zone 2 Frozen Elephant Trunk (FET) is increasingly preferred over Zone 3 FET due to technical simplicity and reduced risks of spinal cord injury, visceral ischemia, and cardiovascular sequelae.
